Description
Covert Threads Fire Retardant Sock. Built for Heat, Strength, and Long Shifts. Ideal for Firefighters, Welders, and Industrial Work in High-Temperature Environments. The Fire Sock is engineered for those who face the heat head-on. Designed for firefighters, welders, and industrial professionals, this sock delivers dependable comfort and protection in demanding conditions. Its flame-resistant fiber blend helps shield against high temperatures, while moisture-wicking technology keeps your feet dry and cool through long hours on the job. Reinforced heel and toe zones provide lasting durability, and compression arch support ensures a secure, stay-put fit under heavy-duty boots. Soft cushioning absorbs impact and reduces fatigue, making every step more comfortable when the work doesn’t stop. Tough, breathable, and built to perform—because when the heat rises, so should your gear. Proudly Made in the USA.
